Bryant-Li-Bhoj syndrome (BLBS; OMIM # 619720, 619721), caused by germline H3F3A and H3F3B variants encoding histone H3.3, is characterized by mild to severe developmental delay, intellectual disability, failure to thrive, muscle tone abnormalities, and dysmorphic facial features. Here, we present a Japanese patient with a novel heterozygous p.A48G variant in H3F3A, displaying previously unrecognized symptoms of neonatal myoclonus. This case helps broaden the phenotypic spectrum of BLBS.

Introduction: Myasthenia gravis (MG) is an autoimmune disorder characterised by autoantibodies against the acetylcholine receptor (AChR-Ab). Morvan syndrome (MoS) is a rarer autoimmune disease with neuromyotonia, dysautonomia and encephalopathy, associated with antibodies targeting contactin-associated protein-like 2 (CASPR2) and may coexist with MG, particularly in patients with thymoma.
Case Report: A 57-year-old man with AChR-Ab MG was treated with pyridostigmine and prednisone for one year and then presented with a severe exacerbation.

Background: Opsoclonus is often associated with serious neurological and paraneoplastic pathology. Pediatric ophthalmologists play an important role in its diagnosis.
Methods: This study was a retrospective chart review of patients seen for suspicion of opsoclonus.

Metachromatic leukodystrophy (MLD) is a rare autosomal recessive lysosomal storage disorder caused by disease-causing variants in the gene coding for arylsulfatase A, leading to deficient enzyme activity and subsequent accumulation of sulfatides. MLD is characterized by demyelination and neurodegeneration of the central and peripheral nervous system, manifesting as progressive motor and cognitive defects in affected individuals. This review provides a comprehensive overview of the significant progress made in MLD research in the past decade, regarding natural history, disease and treatment mechanisms, and newborn screening (NBS).

Unlabelled: Kinesin family member 5 A (KIF5A) is a neuron-specific molecular motor involved in anterograde transport. KIF5A mediates a wide range of trafficking processes that are only partially shared with the other members of the KIF5 family. Since 2002, several disease-causing mutations have been found in the gene and a link between the specific domain in the encoded protein affected by mutations and the associated phenotype has become evident.
